Ubuntu Networking :: Slow/unstable Internet Connection On 10.04

Oct 27, 2010

I have Ubuntu running on my HTPC and for the longest time all this was working fine. Now all of the sudden my Internet connection is all sorts of slow. Chrome browser, transmission bt, apt-get, all have the same speed issue. I tried disabling IPv6, changing my DNS and installing all the latest updates. Nothing works.

I configured manually it but it doesn't works well. I set up the DHCP server on Windows 2003 so I tried to configure it with dhcp too. It gives addresses from 192.168.1.200 to 192.168.1.240 there are no PCs connected with DHCP at the moment, so my IP is only mine.

It takes a lot of time connecting to a internet web site! It's really strange because downloading a file the transferring rate is good, it takes some time starting, but it works normally. I wait almost 7 seconds after seeing a web site. All the others PC's (windows xp) can connect perfectly to network using static and DHCP. Trying with another wire in another room I've got the same result. My /etc/resolve.conf is configured with the IPs specified upper in this page.

I set up my linux router as a simple NAT router. I use CentOS 5.4. When I set up ISP proxy IP in the browser of client PC, Internet access is fast. When I remove ISP proxy IP from the browser, Internet access is slow.

ISP use transparent caching but I can use manual caching as well. Clients on my network with transparent caching get slow internet access and using ISP proxy get fast internet access.

ISP announce that we can use transparent caching or manual caching.

So, I set up my linux router with squid. I set up cache_peer TAG point to ISP's proxy IP. But the problem is the same. Using my squid proxy is slow and using ISP proxy directly is fast. All other network settings are correct.

How can I improve my internet connection using transparent caching. I don't want to set up proxy IP address on all clients.

I bought a new Laptop 2 week ago. It works well, but internet connection ist very slow. I use cable internet speed 25Mbit/s, normal with my old Laptop (Window xp) I can DL with speeds ca.1 Mbit/s but with this new ca. 15 kbit/s (same file). too much different!!! If anyone know, how to troubleshoot this problem, please tell me. And i get a advice that i should crate a new connection using the "workgroup" model instead. I've tried to do but failed. Who knows "how to" please explain it for me.

I've installed recently Ubuntu 11.04 and the first problem that I had was with my wireless lan card Wl-138g V2. The card was not enabled by the system, however after following one of Ubuntu's forum thread I managed to solve it, but... and there is always a but the internet speed is very low.When I had windows installed I faced the same problem and it was solved with an update in the driver, does any one experienced the same in Ubunutu? How did you solve it?

I've just installed Ubuntu 9.10 in my laptop. Everything works fine except for my wireless. It works, but much, very much slower the through RJ45, which is perfectly ok. When using wireless i can't even connect to any online messaging service and I need to reload pages oftenly. My security setting is WEP 128 bits ASCII and since I'm trying to follow the format suggested on the thread "HOWTO post a Wireless issue" I'll try to provide the infos like requested on it. Laptop brand and model (I'm from Brasil, so it's a brasilian model)

I'm going to start using Debian as my desktop system rather than Ubuntu since I'm not really liking all the crazy eye candy and just wanted a fast and simple system. My main problem is networking, I guess I'll start off with my system specs and other information for problem solving.

I have a Realtek RTL8111/8168B Ethernet Adapter builtin to my motherboad which I am using, I could only get a basic connection, by basic I mean that it allowed me to connect to my local area network but not the internet. I then modified /etc/NetworkManager/NetworkManager.conf to change to managed=true this allowed me to use the internet, but the problem is, that it is a very unstable connection, the speed is very slow and it drops a lot! I have to carry on running /etc/init.d/network-manager restart twice to get my connection back, which lasts for about a minute.

I just got my internet working through the wireless card with some help. However, my downloading speeds are beyond extremely slow. While I type on this computer, I am downloading things @ ~500-700kb/s, but when I try to download the package updates etc for my Ubuntu 9.10 laptop, It downloads @ ~ 4k b/s- which is UNBEARABLY slow, putting me at 14h left to complete a 200 mb update.

I've been troubleshooting this problem for several hours now and I'm out of ideas. My internet connection is fine in Windows 7 but an older computer I resurrected (AMD Athlon 1.7 GHz, 512 MB RAM, Fedora 14 Security Lab Spin) is having the stop-and-go's with its internet connection. It will work for very briefly, then it gets extremely slow, where any page I try to navigate to in Firefox 3.6 takes forever to load.I have a DSL connection and my DSL modem is connected to a Linksys WRT54G2 router. I set up a static IP in Windows but don't know how to do this yet in Fedora 14, and I need to get my internet connection working so I can troubleshoot further, but with it being so slow, I'm having to use Windows to search for problems and then switch over to the Fedora box via KVM (IOGEAR), which I also just started using. I don't think that would be related, but who knows.

I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.

Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?

I am succesfully installed a Dell wireless card with Broadcom 4328 shipset using ndiswrapper and rpm sources on Fedora 12 2.6.32.14-127.fc12.i686.PAE. Now I am using original Win drivers but the wifi conection is very slow and unstable.

I understand that wireless is one of the most common problems with Linux, although I did not have this experience with past distributions or versions. After two years away from Ubuntu I installed 10.04 and everything is working fine except the wireless connection. Actually, it does work and connect, but goes up and down, loses connection and in most cases does not reconnect, unless I am 1 meter from the router. The room next door is already too far, a place where I normally have my laptop connecting perfectly with XP.

I'm using an Atheros ath9k wireless card that has been pretty stable since Ubuntu 9.04. I did a clean install of Natty and ever since my wireless connection has been pretty unstable.

It doesn't actually disconnects but I lose all connectivity. The wifi card continues loaded with a static IP Address assigned to it but I cannot connect to anything. The only way to fix it is restating the network manager and I have to do it at least a couple of times every day.

I tried to whitelist ath_pci on /etc/modprobe.d/blacklist-ath_pci.conf but the problem still persists. Also yesterday I enabled the ubuntu backports on my software sources but so far no kernel updates.

Since I upgrade to Ubuntu 10.04 my wireless connection is very unstable. I install the needed wireless drivers from 'Hardware Drivers' (Broadcom STA wireless driver) and I got wireless connection, but it randomly disconnect, and also connection is very slow.

I think that the problem are the drivers which are not very compatible with this version of Ubuntu, which means we need to wait for update? I have HP ProBook 4510s laptop, Intel PRO/Wireless 5100 AGN network card & Gembird NSW-R2 router. I'm only having this problem on Ubuntu 10.04, on other OS's the internet is fine.

I have dual boot OS and I'm using Ubuntu with Win 7. Previously I was using Fedora but I thought to change the flavor! So I installed Ubuntu, but now I'm truly facing problem with my Internet connection! Its too slow in Ubuntu, the both surfing and downloading speed! Usually in windows I get 200-400 kbps download speed when downloading a file and if I download the same file in Ubuntu using flashget I'm getting only 60-70 kbps speed! Also the surfing is too slow! My broadband's bandwidth is 2.1 Mbps!

Like the title, that is my problem. I'm using cable modem with 3mbps. It is Linksys Docsis, wired networking. When I download a file using ubuntu 9.10, my latency time (ping time) sky rocketed to 2000ms average, while in XP none of this happens; I tried to download the same file from the same website. In ubuntu 9.10 my network setup will be, well... nothing. I'm using DHCP automatic detection. Same thing in XP.

I don't want to go back and forward using XP for the internet. Funny thing though, none of this happens while I first started ubuntu 9.10. I didn't configure anything with networking. It is the way it is from the beginning. The only thing I tried was ubuntuone. But that like months ago, and the problem I have with slow internet connection only appear this March.

I am using Ubuntu 10,04 with a gnome interface on an ASUS K70IJ. It all works well, just the internet connection is sometimes blocked or very slow. I have tried it on several places (offices, hot spot, friends) with wireless lan and ethernet. I thought it might be a problem with the pilot for the internet connection. Can anybody tell me where I could find such a pilot and how I do to install it?

I recently installed Kubuntu 10.10 on my machine, and I configured the PPTP VPN connection through which I connect to the internet. I can successfully connect, but it works really slowly. Slower than it does on Windows 7 on the same computer, with the same settings for the PPTP dialer. In about 20 minutes after I connect, the connection fails and even the modem restarts itself. I tried setting the MTU for the pptp connection to 1400 (I checked, and 1372 is the maximum value before the packets start to fragment + 28 bytes for the IP/ICMP headers), but nothing seems to help.

I upgraded to ubuntu 10.04 lts yesterday. The upgrade went smoothly. but now I have a very slow internet connection. It is as if I am on a dial up when I have a broadband speed of 20 MB. What can I do to fix or perhaps roll-back the installation to the previous proper working state.

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

my installed windows makes full use of the 32mbit connection. in fedora i get between 10kbit and 100kbit.this is very annoying especially while browsing the net or using the package manager to do updates or download new software. what could be the problem and how could i solve it?

i very much like the look and feel of fedora 15, but this just makes it unusable on a daily basis.

So far i have tried ubuntu. seems great however i've had trouble with internet connection and soundcard problems. (slow internet connection and poor sound quality. I was thinking of trying kubuntu. Do you think i'll have the same problems?

I have Fedora 14 installed on my s/m with the default gnome desktop environment. Now, I want to install some KDE applications which I found to be very useful. I want to install KDE from fedora 14 DVD as my internet connection is very slow. It was a failure when I tried pointing the yum.repos.d/fedora.repo file to DVD to install using yum. Should I create a repository like what we do in RHEL to configure yum server(How to do it in fedora ???) Or is there any other method to install KDE repository on my system.

I have recently moved countries and have finally got my internet connected today after a lengthy wait. I have a pretty fast connection - it's a fibre connection at approx 100Mbps Between my onu (modem) & computer (Lenovo SL510) I have a cisco wrt120N wireless router. I'm using Opensuse 11.3 (also dual boot with Win7)

My problem is . . . When I enter url in firefox (4) I get the message "looking up www. . ." for approx 5 to 15 seconds before anything starts to load. I also have the same behaviour in konqueror, firefox and yast software manager.

If I use Google Chrome the pages load instantly. Even never before visited pages.

A typical webpage such as Stuff.co.nz - Latest New Zealand News & World News, Sports News & NZ Weather Forecasts takes approx 20 to thirty secs to load in firefox and 3 seconds in Chrome. I can see the same behaviour always whether Chrome used first or firefox used first - so cache does not appear to be the issue.

If I boot into Win7 - websites load instantly there also.

I have updated to the latest wireless drivers for my system - but the behaviour is also evident if I attach a lan cable.

When using anything that involves flash on google chrome, often the flash player crashes going black with an unhappy jigsaw piece inside. it also struggles at handling multiple tasks in different tabs. i know that adobe flash player is not designed for ubuntu, and will not run at optimum level, but i would like to know if anyone has done or knows anything that will make it more stable/quick.

I am running FC13 on a Compaq Presario 2100 using a Broadcom BCM4306. I was able to get it running thanks to Fedora Unity Project. But It's a very unstable connection. I don't know what settings to adjust or enable or disable. It's not my router, this is the only wireless connection in the house that I have trouble with.
